A cylindrical steel tank which is part of a process cycle with about 250l Volume about 2m high and 45cm in diameter needs to be sealed to atmosphere. The system is not pressurised.
Depending on the process the tank is filled with different liquid levels. E.G. filled 1.2m or 1.6m or 1.8.....)
Between the free liquid surface and the lid there should be no gap.
Does anyone now some equipment which acts as a kind of floating lid. (A little bit similar to the movable gas storage tanks) I looked on the internet but I was not able to find anything. Ideally The lid should float on the liquid surface. When the liquid expands due to temperature change (temperatures can change from 20 to 80°C)the lid should move also. There should be no gap between cylindrical tank wall and lid in order to avoid los of liquid due to evaporation. I could invisage kind of O-rings which are inflatable. Does anyone know whether such an device exist, what is the product name are there supliers.
